by Happymodel

The Happymodel Mobula8 O4 2S Micro Digital HD FPV Whoop is an 85mm micro whoop drone equipped with the DJI O4 Air Unit HD digital video system. Built on a durable 85mm ducted frame, the Mobula8 O4 combines high-definition 1080p 100fps video transmission with the agility and crash protection of a 2-inch micro whoop.

Powered by high-rpm EX1103 11000KV brushless motors spinning Gemfan Hurricane 2023 tri-blade propellers, the drone delivers responsive freestyle punch and stable outdoor handling on 2S LiPo power. The integrated CrazyF405HD AIO flight controller houses an STM32F405 processor, 12A BLHeli_S/Bluejay ESCs, an onboard barometer, and a built-in UART ExpressLRS 2.4GHz receiver. Happymodel includes a dedicated camera FOV extender and an ND filter set (UV, ND8, ND16) to widen the DJI O4 camera field of view up to 150 degrees for immersive flight recording.
